hemokoncentration

Hemoconcentration refers to an increase in the proportion of red blood cells and other blood components relative to plasma, resulting in a higher concentration of blood. This phenomenon occurs when there is a loss of fluid from the plasma, without a corresponding loss of blood cells. Consequently, the blood becomes thicker and more viscous.

Several factors can lead to hemoconcentration. Dehydration is a common cause, where insufficient fluid intake or excessive fluid loss through sweating, vomiting, or diarrhea reduces the overall plasma volume. Burns can also cause hemoconcentration due to fluid leakage from damaged blood vessels into surrounding tissues. Certain medical conditions, such as diabetes insipidus, can contribute by increasing urination and fluid loss. Additionally, the use of diuretics can also lead to a reduction in plasma volume.

In a clinical setting, hemoconcentration is often detected through laboratory tests that measure hematocrit or hemoglobin levels. An elevated hematocrit, which represents the percentage of blood volume occupied by red blood cells, is a key indicator of hemoconcentration. While hemoconcentration itself is a sign of an underlying issue, it can also have direct consequences. Increased blood viscosity can impair circulation, potentially leading to a higher risk of blood clots. Managing the underlying cause of fluid loss is the primary approach to addressing hemoconcentration.
